React Native Eth Daemon

Getting started

$ npm install react-native-eth-daemon --save

Mostly automatic installation

$ react-native link react-native-eth-daemon

Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-eth-daemon and add RNEthDaemon.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNEthDaemon.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainActivity.java

• Add import com.reactlibrary.RNEthDaemonPackage; to the imports at the top of the file
• Add new RNEthDaemonPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-eth-daemon'
   project(':react-native-eth-daemon').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-eth-daemon/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-eth-daemon')
   

4. It's necessary to add to "build.gradle(Project)" this:

     allprojects {
       ...
       flatDir {
         dirs "$rootDir/../node_modules/react-native-eth-daemon/android/geth"
       }
     }
   

Add the Geth framework

After you added this project successfully to your's, there is still one thing left todo. You need to "include" the GethFramwork in your project. Follow the instructions to include the framework in your project.

Android

Open the "android" project of your React-Native app in Android Studio and add to "build.gradle(Project)" this:

allprojects {
    ...
    flatDir {
        dirs "$rootDir/../node_modules/react-native-eth-daemon/android/geth"
    }
}

iOS

First add to your project's "Build Phases" the following:

• Target Dependencies: RNEthDaemon
• Link Binary With Libraries: Geth.framework (you will need to search it inside ../node_modules/react-native-eth-daemon/ios/Frameworks)

Then, add to your project's "Build Settings", into "Framework Search Path": $(PROJECT_DIR)/../node_modules/react-native-eth-daemon/ios/Frameworks (recursive)

Usage

import RNEthDaemon from 'react-native-eth-daemon';

And then use the functions startDaemon/stopDaemon as follow inside your JS:

async function startFunction() {
  try {
    let result = await RNEthDaemon.start({
      enabledEthereum:true,
      networkID:3,
      enodesNumber:16,
      maxPeers:25,
      enabledWhisper:false
    });
    if (result == null) {
      Alert.alert('Node successfully started! :D');
    }
  } catch(e) {
    Alert.alert(e.message);
  }
}

async function stopFunction() {
  try {
    let result = await RNEthDaemon.stop();
    if (result == null) {
      Alert.alert('Node successfully stopped! :D');
    }
  }  catch(e) {
    Alert.alert(e.message);
  }
}
